YMMV. These products were originally spotted at the Covington, WA location but are not guaranteed to be in stock by the time you visit that Costco warehouse location.
Price and participation may vary so it may not be available at your local Costco or it may not be on sale at your local Costco or it may be a different price at your local Costco.
Prices & sales dates may change at any time without notice.
Products may sell out before the end of the sale date and they might not get restocked.
This list does not represent everything that is on sale at Costco.
A lot of products at Costco are seasonal items and when they sell out, they are not restocked.
Some products are sold regionally and other products are sold nationally.
Some products sold nationally may not be on sale at all Costco locations.
Costco inventory changes constantly and I do not have access to that information.
Photos may not be a perfect representation of the product.
Color of the product in real life may vary from the photo.
Unadvertised sales or secret sales in this post are sales that are not included in the Savings Book (aka, the coupon book).
This is just a posting of a deal and not an endorsement or recommendation of any product or of Costco. Please do your own research before making any purchase.
